Hereinafter, an embodiment of the ceiling structure for the indoor partition and the indoor partition will be described with reference to FIGS. 1 to 7.
As shown in FIG. 1, in the indoor partition 200 in the present embodiment, the upper side of the frame bodies 20 facing each other in the connecting frame 10 is connected by the ceiling member 210. In other words, the ceiling member 210 constitutes the ceiling structure for the interior partition. The connecting frame 10 is configured by connecting the first partition frame 111, the second partition frame 112, and the third partition frame 113 with a connecting member. The first partition frame 111 and the second partition frame 112 are connected by a connecting member so that the frames are orthogonal to each other, and the frames of the second partition frame 112 and the third partition frame 113 are arranged side by side in the width direction. It is connected by a connecting member as described above. As a result, the thickness direction of the second partition frame 112 and the third partition frame 113 is supported by the first partition frame 111, and the connecting frame 10 can stand on its own. The second partition frame 112 and the third partition frame 113 are composed of the same frame body 20. The first partition frame 111 is composed of the second partition frame 112 and the frame body 20B which is similar to the frame body 20 except that the length in the width direction is short. Therefore, in the present embodiment, the frame body 20 will be described, and the description of the frame body 20B will be omitted below.

The frame body 20 is configured as a rectangular frame, one of the two pairs of opposite sides is the upper support column 20a and the lower support column 20b, and the other opposite side is the left support column 20c and the right support column 20d. Further, in the present embodiment, in the plane including the frame body 20, the direction within the range surrounded by the frame body 20 is set as the inner peripheral side of the frame body 20, and the range outside the range surrounded by the frame body 20 is set. Is the outer peripheral side.

In the frame body 20, the upper column 20a and the lower column 20b are arranged horizontally with respect to the floor surface, and the left column 20c and the right column 20d are arranged vertically with respect to the floor surface. The frame body 20 forms a rectangular shape by connecting each of the two orthogonal columns of the four columns at right angles with the square member 30. In the present embodiment, it is assumed that the longitudinal direction of the left strut 20c and the right strut 20d is the vertical direction, and the longitudinal direction of the upper strut 20a and the lower strut 20b is the left-right direction.

The frame body 20 includes legs 14, 15 that support the second or third partition frames 112, 113 in a non-contact manner with respect to the floor surface. The upper strut 20a and the lower strut 20b each have an accessory mounting portion 212 composed of a plurality of through holes 27 at the ends in the left-right direction, and the lower strut 20b uses the through hole 27 of the accessory mounting portion 212. Then, the legs 14 and 15 are attached.

In the frame body 20, two horizontal bars 25 are hung between the left strut 20c and the right strut 20d at positions different from each other in the vertical direction. The left strut 20c and the right strut 20d have a plurality of through holes 27 arranged at predetermined intervals in the vertical direction, and the horizontal bar 25 is attached by using the through holes 27. One end of the horizontal bar 25 is fixed to the through hole 27 of the left strut 20c, and the other end is fixed to the through hole 27 of the right strut 20d. Further, the horizontal bar 25 is arranged so as to be horizontal to the upper support column 20a and the lower support column 20b.

The upper support column 20a and the lower support column 20b are composed of short columns 21 having the same structure. Further, the left strut 20c and the right strut 20d are composed of a long strut 23 having the same structure. The short strut 21 and the long strut 23 are columns composed of similar square tubes extruded from a metal material containing aluminum as a main component, and extruded continuous tubes are cut to different lengths. The difference is that the positions where the through holes 27 are provided are different. The long strut 23 has a length L2 in the longitudinal direction, and the short strut 21 has a length L1 shorter than the length L2 in the longitudinal direction.

The short columns 21 (upper column 20a and lower column 20b) will be described with reference to FIG. Since the long strut 23 is composed of a square tube having a rectangular cross section similar to that of the short strut 21, detailed description thereof will be omitted.

The short strut 21 is composed of a square tube having a rectangular cross section, includes an outer peripheral side surface 21a and an inner peripheral side surface 21b facing each other in parallel, and is parallel to the outer peripheral side surface 21a and the inner peripheral side surface 21b. It is provided with two side surfaces 21c and 21d facing each other.

The outer peripheral side surface 21a and the inner peripheral side surface 21b form a rectangular long side at the end surface of the short support column 21. In the frame body 20, the outer peripheral side surface 21a is arranged on the outer peripheral side, and the inner peripheral side surface 21b is arranged on the inner peripheral side.

The two lateral sides 21c and 21d form a rectangular short side at the end face of the short support column 21. In the frame body 20, the lateral side surfaces 21c and 21d are arranged in the left-right direction which is a direction orthogonal to the inner peripheral side or the outer peripheral side.

In this embodiment, the length W1 of the long side of the rectangle is longer than the length T1 of the short side of the rectangle.
The short column 21 has a width guide 211 as a protruding portion protruding from both ends of the outer peripheral side surface 21a in the lateral direction with respect to the outer peripheral side surface 21a, respectively. The width guide 211 extends in the longitudinal direction of the short support column 21 and has a wall-shaped portion 214 projecting at a predetermined height T3 in a direction orthogonal to the outer peripheral side surface 21a. The wall-shaped portion 214 is provided with an overhanging portion 213 projecting above the outer peripheral side surface 21a at a tip portion separated from the outer peripheral side surface 21a. The overhanging portion 213 has a surface parallel to the outer peripheral side surface 21a and has a predetermined overhanging length W4. A predetermined space is secured with a width W3 between the overhanging portions 213 on both sides of the outer peripheral side surface 21a. The length of the length W1 of the long side of the rectangle is equal to the length of the width W3 plus the two predetermined overhang lengths W4. Further, the distance between the two wall-shaped portions 214 is the wall-to-wall width W2, and has a relationship of the length W1 of the long side of the rectangle> the wall-to-wall width W2> the width W3.

The accessory mounting portion 212 of the short column 21 is composed of two through holes 27 arranged side by side at predetermined intervals along the longitudinal direction.
The short strut 21 includes a screw receiving portion 26 extending in the longitudinal direction of the short strut 21 in the internal space. The screw receiving portion 26 has a base end supported on the inner surface of the pipes of the lateral side surfaces 21c and 21d, and the tip to which the screw is screwed protrudes into the space inside the square pipe and is arranged at a predetermined position. A predetermined distance is secured between the two screw receiving portions 26 facing each other.

Here, the screw receiving portion 26 will be described in detail.
The screw receiving portion 26 includes a support leg 261 extending from the inner surface of the lateral side surfaces 21c and 21d to the space inside the square tube, and a female thread portion 262 attached to the tip of the support leg 261. The support legs 261 are extended in a direction orthogonal to the lateral side surfaces 21c and 21d to which the base end is fixed. The female thread portion 262 has a semi-cylindrical shape having a notch 263 in a part of the circumference. When a screw having a thread having an outer diameter slightly larger than the inner diameter of the semi-cylinder is screwed, the notch 263 is screwed together with a female screw being formed on the inner peripheral surface 264 by the expansion pressure received from the screwed screw. Appropriate diameter reduction force is applied to the screw. Therefore, the female screw portion 262 applies a fastening force to the screwed screw in the screwing direction and maintains the fastening force.

The short column 21 is provided with two through holes 27 that can be used for positioning and the like of parts provided at the open end 21f. The two through holes 27 are arranged side by side in the longitudinal direction at positions close to the opening end 21f of the short column 21. The through holes 27 are provided at different positions in the short columns 21 and the long columns 23, but their structures are the same.

The through hole 27 includes a circular inner hole 28 that opens on the inner peripheral side surface 21b and a circular outer hole 29 that opens on the outer peripheral side surface 21a. The diameter D1 of the inner hole 28 is smaller than the diameter D2 of the outer hole 29. The diameter D1 and the diameter D2 are concentric circles centered on one vertical line perpendicular to the outer peripheral side surface 21a and the inner peripheral side surface 21b. For example, a convex portion having a screw hole formed on the top surface of a cylinder that can be inserted into the outer hole 29 is provided in the connecting member 50 or the cover member 40, and the convex portion is inserted into the outer hole 29 toward the inner hole 28. Subsequently, a screw is screwed into the screw hole of the convex portion from the outer hole 29 toward the inner hole 28. The screw is screwed into the inner hole 28 to fix the convex portion at its head. As a result, the connecting member 50 (see FIG. 1) and the cover member 40 (see FIG. 1) provided on the outer peripheral side surface 21a are fixed to the outer peripheral side surface 21a by the tension generated by the screwing of the screw to the convex portion. Therefore, the predetermined distance between the two thread receiving portions 26 facing each other has at least a longer distance than the large diameter D2.

The structure of the leg portion 15 (see FIG. 1) of the frame body 20 will be described with reference to FIG.
In the frame body 20, the short strut 21 and the long strut 23 are connected and fixed via the square member 30 so that the longitudinal direction of the short strut 21 and the longitudinal direction of the long strut 23 are orthogonal to each other. The square member 30 is arranged at a position including a portion where the longitudinal direction of the short column 21 and the longitudinal direction of the long column 23 are orthogonal to each other, and is arranged so as to be sandwiched between the short column 21 and the long column 23. Has been done. In the present embodiment, the short strut 21 and the long strut 23 are not in contact with each other, and the short strut 21 and the long strut 23 are fixedly connected with the square member 30 interposed therebetween.

The cover member 40 is attached to the short column 21 via the two through holes 27 of the accessory attachment portion 212. In the cover member 40, the first cover portion 42 is fixed to the outer peripheral side surface 21a and covers a part of the outer peripheral side of the square member 30, and the second cover portion 43 covers the other portion of the outer peripheral side of the square member 30. More specifically, the first cover portion 42 is a portion in which the outer peripheral side surface 21a is extended in the longitudinal direction of the short support column 21. The second cover portion 43 is a portion extending from the tip of the first cover portion 42 extending to the lower part of the square member 30 toward the long support column 23. Further, the first cover portion 42 and the second cover portion 43 have a shape that covers the outer peripheral side surface of the square member 30 so that the heads of the screws fastened to the square member 30 cannot be seen.

The square member 30 is a plate-shaped first pressure contact portion 32 having a pressure contact surface 32a that abuts on the opening end 21f of the short support column 21, and a plate material-like first pressure contact surface 34a that has a pressure contact surface 34a that abuts on the opening end 23f of the long support column 23. It is provided with a two pressure contact portion 34. The square member 30 is arranged so that the relative angle between the pressure contact surface 32a and the pressure contact surface 34a is 270 degrees. In other words, the opposite surface of the pressure contact surface 32a and the opposite surface of the pressure contact surface 34a are arranged so as to face each other at a relative angle of 90 degrees. Further, square member side walls 31 as a plane including the side surface of the opposite surface of the pressure contact surface 32a and the side surface of the opposite surface of the pressure contact surface 34a are provided on both side surfaces of the square member 30. The square member side wall 31 has a plate shape including a surface included in the same surface as the lateral side surfaces 21c and 21d of the short column 21 and the lateral side surfaces 23c and 23d of the long column 23. The side walls 31 of the square member are provided on both side surfaces of the square member 30 with a size that does not protrude from the outer periphery of the rectangle formed by the frame body 20. Specifically, the square member side wall 31 shows an appearance in which the width guide 211 of the short strut 21 is extended by the length L31 and the width guide 231 of the long strut 23 is extended by the length L32 on the square member 30. It is provided in an embodiment. The first cover portion 42 and the second cover portion 43 described above have a width W44 and a width W45 that can be arranged between the two square member side walls 31, and enter between the two square member side walls 31. It is arranged in the form.

The square member 30 has an inner peripheral surface 37 which is a surface facing the inner peripheral side. The inner peripheral surface 37 has a first margin portion 371 having a margin corresponding to the thickness of the first pressure contact portion 32 in the longitudinal direction of the short strut 21, and the second press contact portion 34 in the longitudinal direction of the long strut 23. It has a second margin portion 373 having a margin corresponding to the thickness of the above, and a continuous portion 372 connecting the first margin portion 371 and the second margin portion 373. Since the inner peripheral surface 37 has a predetermined distance, at least a predetermined distance is secured between the opening end 21f of the short column 21 and the opening end 23f of the long column 23. Therefore, the short strut 21 and the long strut 23 are connected and fixed via the square member 30 in a separated manner. Further, the length L31 is continuous with the first margin portion 371 of the square member 30 in addition to the length T1 of the short side of the rectangle of the long support column 23 and the predetermined height T3 of the width guide 231. The length is the sum of the length generated by the portion 372. Further, the length L32 is a length obtained by adding the length T1 of the short side of the rectangle of the short strut 21 and the predetermined height T3 of the width guide 231 to the length T3 and the second margin portion 373 of the square member 30 and the continuous portion. The length is the sum of the length generated by 372 and the like.

Then, the screw hole 33 of the first pressure contact portion 32 was inserted in a state where the pressure contact surface 32a of the first pressure contact portion 32 of the square member 30 was in contact with the open end 21f of the short column 21 corresponding to the lower support support 20b. The bolt B2 is screwed into the inner peripheral surface 264 of the screw receiving portion 26 of the short column 21 at the tip of the screw hole 33. As a result, the square member 30 is fastened and fixed to the short support column 21.

A bolt through which the screw hole 35 of the second pressure contact portion 34 is inserted while the pressure contact surface 34a of the second pressure contact portion 34 of the square member 30 is in contact with the open end 23f of the long support column 23 constituting the right support column 20d. B3 is screwed into the inner peripheral surface 264 of the screw receiving portion 26 of the long support column 23 at the tip of the screw hole 35. As a result, the square member 30 is fastened and fixed to the long support column 23. Since the second pressure contact portion 34 is thick, the screw hole 35 is an enlarged diameter portion 352 in which the head of the bolt B3 can enter in front of the insertion hole 351 through which the portion having the screw groove in the bolt B3 is inserted. have.

After the short strut 21 and the long strut 23 are connected and fixed by the square member 30, the cover member 40 is attached to the outer peripheral side surface 21a of the short strut 21.
The cover member 40 has a columnar convex portion 44 that can be inserted into the outer hole 29 of the through hole 27 on the side surface of the first cover portion 42 facing the outer peripheral side surface 21a. The convex portion 44 has a screw hole formed on the end surface in the direction of insertion into the outer hole 29, and the bolt B1 inserted through the inner hole 28 of the inner peripheral side surface 21b of the short support column 21 is screwed into the convex portion 44. The extending length of the convex portion 44 is shorter than the length of the short side T2 (see FIG. 2) in the square tube. Therefore, the surface of the cover member 40 having the convex portion 44 is abutted and fixed to the facing outer peripheral side surface 21a based on the fastening force applied to the convex portion 44.

Further, the cover member 40 has a width W44 which is a width that falls within the width W3 between the width guides 211. The width W44 is the width at which the cover member 40 is positioned by the width guide 211, and is set to a width that is equal to or less than the width W3 but such that a large gap is not formed between the cover member 40 and the width guide 211. In the cover member 40, the first cover portion 42 has a length L3, and the second cover portion 43 has a length L4. The length L3 of the first cover portion 42 covers the two through holes 27 of the accessory mounting portion 212 of the outer peripheral side surface 21a, and extends the opening end 21f of the short strut 21 in the direction of the square member 30 to form the square member 30. It is the length to the position exceeding the screw hole 35 of the second pressure contact portion 34. Further, the length L4 of the second cover portion 43 is a length that reaches the opposite surface of the pressure contact surface 34a of the second pressure contact portion 34 from the tip of the square member 30 of the first cover portion 42. As a result, in the square member 30, the opposite surface of the pressure contact surface 32a of the first pressure contact portion 32 and the opposite surface of the pressure contact surface 34a of the second pressure contact portion 34 are covered by the cover member 40 together with the bolts B2 and B3, and the square member 30 is apparently covered. The design of the product has been enhanced. Further, the cover member 40 has a thickness T6 of which is equal to or larger than a predetermined height T3 of the width guide 211. As a result, there is little possibility that the cover member 40 will enter under the overhanging portion 213 of the width guide 211 and an unnecessarily wide gap will be created between the first cover portion 42 and the width guide 211.

The first cover portion 42 has a columnar leg adjusting portion 45 on a surface on the side not facing the outer peripheral side surface 21a. The leg adjusting portion 45 is provided with a screw hole 45h at an end separated from the first cover portion 42, and a screw portion 413 provided on the opposite side of the ground plane 412 of the leg 41 is attached to the screw hole 45h by screwing. Since the distance between the leg adjusting portion 45 and the ground contact surface 412 changes depending on the screwing amount of the leg 41, the leg adjusting portion 45 can be expanded and contracted so that the ground contact surface 412 is suitably in contact with the floor surface.

The leg adjusting portion 45 is provided at a position where the opening end 21f of the short column 21 of the first cover portion 42 is past the direction of the square member 30, but the base end of the first cover portion 42 is on the inner peripheral side surface 21b. It is supported, and the tip thereof is supported on the opposite surface of the pressure contact surface 34a of the second pressure contact portion 34 via the second cover portion 43. Therefore, the possibility that the first cover portion 42 is deformed by the load pushing the floor surface is suppressed.

As shown in FIGS. 4 to 6, a ceiling member 210 is attached to the outer peripheral side surface 21a of the frame body 20 via a mounting bracket 150. Here, a case where two mounting brackets 150 are attached to the upper support column 20a will be described.

As shown in FIG. 4, the ceiling member 210 connects the first member 20e arranged in the vertical direction from each of the upper columns 20a of the two frame bodies 20 and the first member 20e of each of the two frame bodies 20. The second member 20f is provided so as to be horizontally arranged. The first member 20e and the second member 20f each have a different length in the longitudinal direction from the upper support column 20a (short support column 21), but are composed of a square tube having a rectangular cross section similar to the upper support column 20a. .. That is, the first member 20e and the second member 20f each have an opening end 21f similar to that of the upper support column 20a. Therefore, the corresponding pressure contact surface of the square member 30 is pressed against each open end 21f of the first member 20e and the second member 20f, so that the first member 20e and the second member 20f are connected at an angle of 90 degrees. Will be done.

The first member 20e is provided upward along a plane including the frame body 20. The first member 20e has a length L5 that secures a height required in addition to the upper support column 20a when the ceiling member 210 is provided. The length L5 is, for example, a length corresponding to the height required in addition to the upper support column 20a so that the ceiling member 210 does not give a feeling of oppression to the user underneath. In the first member 20e, the opening end 21f at the base end is fixed to the upper support column 20a, and the opening end 21f at the tip end is connected to the second member 20f.

The second member 20f is provided in a direction perpendicular to the plane including the frame body 20, for example, horizontally. The second member 20f has a length L6 capable of connecting two first members 20e provided on the frame bodies 20 facing each other. The second member 20f is connected to the opening end 21f of the first member 20e to which each of the square members 30 pressed against the opening ends 21f at both ends corresponds to each other.

The first member 20e and the second member 20f are similar to those extruded from a metal material containing aluminum as a main component, except that the length (height) is different from that of the upper support column 20a constituting the frame body 20. Similarly, it is a strut composed of a square tube.

Explaining that the mounting bracket 150 has a quadrangle having a vertical width of the second width WA1 and a horizontal width of the third width WB1 as a basic form, the length of the linear vertical side is the second width WA1 and the linear horizontal side. The length of is the third width WB1. In this basic shape, the mounting bracket 150 is cut from the center or the vicinity of the center of the third width WB1 on the horizontal side in the direction of the second width WA1 which is a predetermined circumferential direction when viewed from the rotation axis CA. It is a plate portion 151 having a shape in which a first width WC1 is formed in a missing portion. In other words, the plate portion 151 is composed of a polygonal plate body, specifically, a hexagonal shape having three sets of parallel sides, and a contact surface capable of contacting the outer peripheral side surface 21a of the short support column 21. have. The width of the contact surface of the plate portion 151 is the width of each of the three sets of parallel sides.

On the other hand, the screw holes 156 for mounting the first member 20e or the like on the mounting bracket 150 are provided along the line C156 along the longitudinal direction of the short support column 21 at equal intervals from the rotation axis CA. Since the mounting bracket 150 is arranged at an equal distance from the rotation axis CA on an orthogonal line orthogonal to the longitudinal direction of the short strut 21, the rigidity applied to the two screw holes 157 can be made equal. , The first member 20e and the like can be suitably held.

The mounting bracket 150 is divided into a first portion 155 of the width WB 3 and a second portion 153 of the width WB 2 at the center of the third width WB 1. Thus, when the plate portion 151 is swiveled by the rotation axis CA, the second portion 153 has the narrowest width WA2 at the end adjacent to the first portion 155 and is away from the first portion 155. It has the widest width WD1 in the section.
